A field experiment was conducted during 2001-2003 to evaluate the effect of water stress on the yield and yield components of four rice cultivars commonly grown in Mazandaran province, Iran. In northern Iran irrigated lowland rice usually experiences water deficit during the growing season include of land preparation time, planting, tillering stage, flowering and grain filing period. Recently d...

Grain morphology and crystallographic texture were investigated by electron microscopy in four different polycrystalline forms of superconducting MgB2. The materials included a hot-pressed sintered MgB2 pellet, a pellet reacted in situ from Mg and B, an in situ reacted MgB2 filament and a pulsed-laser-deposited thin film grown on a single crystalline [111] oriented SrTiO3 substrate. Thick plate...

The aim of our study was to quantify changes in the activity of tyrosine decarboxylase (TYDC) within tissues of two cultivars of winter triticale: Triticosecale (Wittm. ex A. Camus), caused by grain aphid, and Sitobion avenae (F.). Obtained results show that Witon cv was less acceptable by S. avenae than Tornado cv and that antibiosis was an important part of the acceptability. The grain aphid ...

background and objectives: iran owns a rich and prestigious heritage of medicinal herbs but the majority of these plants have not yet undergone chemical, pharmacological and toxicological studies. in the present study some species form northern parts of iran were evaluated for cytotoxicity. methods: sixteen medicinal plants were extracted with methanol and screened for their cytotoxic activitie...

In this paper, we propose a hardware/software partitioning method for improving applications’ performance in embedded systems. Critical software parts are accelerated on hardware of a single-chip generic system comprised by an embedded processor and coarse-grain reconfigurable hardware. The reconfigurable hardware is realized by a 2-Dimensional array of Processing Elements. A list-based mapping...
